Building NetSNMP for ARM/atsamv

[Ruhollah Majdoddin]

I try to have RSB to build the NetSNMP package, but it fails. The RSB
and RTEMS kernel  are both 4.12, target architecture is ARM and BSP is
atsamv (arch/bsp are already built in prefix).

As far as I can see,  one problem is that function "isspace" from
cctype is undeclared, and the other is with linking:
linkcmds.base:390 cannot move location counter backwards  (from
00000000204bf480 to 000000002045f000)

Any suggestions?

This is the shell command and output:

$ ../source-builder/sb-set-builder --log=log_atsamv_net_snmp
--prefix=$HOME/mcg/rtems-git/4.12 --target=arm-rtems4.12
--with-rtems-bsp=atsamv net-mgmt/net-snmp.bset
